OFDM channel separation

Proposed AP: resolved through CID 521, 349 and 1145 (These comments have been accepted in Dallas)

Monnerie, Riou, Schmidl,Shimada, Shin

CID 1099

Comment: STF tables could be simplified by using unit entries instead of current values

Commenter’s proposal: Suggestion to allign the STF tables with popular convention by normalising the table to use values of +1 or -1 to designate the tones. Then time domain samples with an rms of 1 can be obtained by multiplying by N/sqrt(ntones). Where ntones are the number of tones used by the STF. Then power boosting can be applied explicitly as desired.

Related comment : CID 1100, 181, 1103, 1106, 1110, 179

2 Proposed resolutions:

Accept

or

Reject

CID 1108 – Data scrambler seed

Comment: Change the scrambler seed for the first line of the table to zeros.

3 Proposed resolutions:

Accept

or

Reject

or

AP: use a PIB attribute to define the scrambler options. The definition of the scrambler option in the PHR introduces some unnecessary delay in the processing.

CID 169 (definition of the bandwidth)

Comment: Definition of nominal b/w needed.

Commenter’s proposal: Clarify that the nominal b/w is the 20 dB b/w of the signal.

3 Proposed resolutions:

Use 20dB bandwidth

or

(N+1)*T where N is the number of active tones, including pilots and T is the tone spacing.
